(Phys.org)—A group of researchers from the University of Groningen in the Netherlands have developed a way to change the handedness of a double-stranded metal helicate by photo and thermal stimulation by attaching bipyridine ...

Three scientists won the Nobel Prize in chemistry on Wednesday for developing the world's smallest machines, 1,000 times thinner than a human hair but with the potential to revolutionize computer and energy systems.

Within each of our cells is a distribution system that uses molecular motors and filaments to move proteins, organelles, and other tiny bits of cargo along its inner framework, or cytoskeleton. To achieve this feat, the motors ...

Human cells contain 23 pairs of chromosomes that form a loosely organized cluster in the cell nucleus. When cells divide, they must first condense these chromosomes—each of which when fully extended is a thousand times ...

Physical chemists have devised a rolling DNA-based motor that's 1,000 times faster than any other synthetic DNA motor, giving it potential for real-world applications, such as disease diagnostics. Nature Nanotechnology is ...

German scientists have developed a new class of molecular motors that rotate unidirectionally at speeds of up to 1 kHz when exposed to sunlight at room temperature. This unique combination of features opens up novel applications ...

A research group jointly fabricated molecular motors on a metal substrate using supramolecules, and successfully reversed their rotation by rearranging bonding between molecules that constitute a supramolecule.
